Extraterrestrials Can Earth be the only place in the Universe that hosts life? Most astronomers don't believe this to be true. Some statistics in the Universe provide evidence that living things may be commonplace throughout the universe, on planets of other stars besides the sun. In this article I intend to discuss the various points of view of those who believe that extraterrestrials exist and have even visited Earth, and the points of view of skeptics who believe that aliens do not exist and have not visited Earth. To get into the topic, he must first start from the base of the subject. First we must address the issue of the fact that life is native only to planet Earth. One of the most basic materials essential to forming life are basic carbon compounds. These carbon compounds are very abundant throughout the Universe. Carbon compounds exist not only on planets but also on comets, floating asteroids, and gas clouds in space. Although, even with the abundance of all these compounds in the Universe, the chances of these compounds forming into living things are not that great, it is true that the chances of carbon forming into compounds that support life increase dramatically with l 'increase time. . The Universe functions on a backward basis compared to the human way of thinking. The Universe becomes more ordered with time while we would tend to think that time breaks down structures. What this means for us is that the chances of life evolving anywhere in the Universe increase with the passage of time. Another factor necessary for the evolution of life is the size of a star. Our Sun is a very ordinary star in terms of size and temperature. Statistics show that in our galaxy alone there are billions of stars like the sun. ( Henbest & Couper, 1989, paragraph 5 ) Life evolving in one of these star systems may have developed in the same way as humans. Philosophers have argued for centuries about how to define life. “If we study living things on Earth, we find that there are some basic characteristics that will guide us when we consider life elsewhere in the Universe.” (Henbest & Couper, 1989, paragraph 7) Life on Earth presents immense diversity. From organisms such as sea snails to humans. All life on Earth is made up of the same basic units, cells. Each cell is made up of carbon chains, the most important... half of the paper... of the existence of extraterrestrials. For many it remains a mystery whether they exist on Earth or even if they exist at all. Saying that extraterrestrials do not exist throughout the Universe is not a valid belief. There are simply too many ways or forms to find life throughout the Universe, intelligent or otherwise. The odds of life on an intelligent or non-intelligent scale in our Milky Way are pretty good in themselves. In my opinion, the Universe merges with life, I can't say for sure whether anyone has visited us, but all this is plausible. I am fascinated by the thought of an advanced civilization aiding humanity in the advancement of our species. I hope that one day we as a race will become morally, socially and politically advanced enough that war of any kind is non-existent and we will live in a world where we get along with each other despite small differences. For an advanced civilization, we must all look the same to each other, they would probably have compassion on human ways and that is why they may have taken it upon themselves to help us advance as a civilization so that we can create a bond with beings of other origin.
